Upgrading Firmware

The camera doesn't need to be plugged into the computer, nor do you need a USB cable. What you need is the battery in your camera charged right up, a clean (no other files on it) SD card that you reformat before you load the dat file onto it and a card reader to download the dat file onto the SD card.

Once the file is on the card, insert the card into your camera and turn the camera on while pressing the DISP/BACK button. Answer OK to all of the questions that you get.
